Detecting wavelength and observing wavelike characteristics

Postby Abigail Urbina 1K » Tue Oct 17, 2017 10:40 pm

Is there a particular "threshold" in length that a wavelength must have in order for us to be able to detect the wavelength or observe its characteristics? What is considered "too small" for us to detect?

Looking at my notes from one of the lectures, I remember Prof. Lavelle saying that anything ≤ 10-15m is too small to detect.

In the examples he used, a classical object had something of a wavelength of 1.64x10-34m, which is way too small. While for example, an electron at 5.3x106m/s would result in a wavelength of 1.4x10-10m, which is normal.
